|Centralized Optimal Control for a Multimachine Power System Stability Improvement Using Wave Variables|
This paper introduces the application of wave variable method in reducing the effect of delay during the transmission of control signals via large distances in a multimachine power system. Fast response and pure control signals applied to a power system have great importance in control process. At first we design a centralized optimal control considering no transport delay and then we compare them to the one considering this effect in order to demonstrate the deteriorating effect of transmission...

This paper deals with the comparison of three types of sub-optimal control law for the stable levitation of a turbojet shaft, sustained by two radial active magnetic bearings (AMBs). Shaft is considered rigid for the procedure simplification. The utilized approach leads to development of different sub-optimal control laws to use in speed-varying simulations in the angular speed of the shaft. The first control matrix is obtained by explicit relationships of the parameters of the control law vs...
